CLOSING DEVICE FOR VESSELS.

Application filed March 28,1906. Serial No. 308.383.

T0 all 1072/0711/ it ntl/ty can/cern.-

Be it known that I, IVILLIAM B. FENN, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in'Closing Devices forVessels g and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the saine.

The object of this invention is to provide more effective means thanhave heretofore been proposed for sealing fruits, meats. or otheredibles in jars or like vessels to secure the same from the deleteriouseqects of exposure to the atmosphere; but my invention can be used forother purposes where effective sealing is desirable or advantageous.

In the accompanying drawings I have shown the invention embodied in theform of a glass In the said drawings, Figure lis a central verticalsectional view of the cover. Fig. 2 is a similar sectional view of thejar with the cover applied. Fig. 3 is an edge view of a sealing-ringwith a quadrant removed, and F ig. 4 is a top plan view of thesealing-ring. F ig. 5 is a top plan view of a ring made of coils.

In the several views, 1 designates a jar, the neck of which isdesignated 2. At a point somewhat below the top of the jar is an annularshoulder 3, and the portion of the neck 14 from this shoulder upward isslightly tapered toward the axis of the jar. This tapered portion isprovided with a thread or threads, which are preferably sharpened toprovide a penetrating edge. The upper end of the neck of the ar is madewith an outwardlyprojecting shoulder 3a, having its outer face slightlytapered inward.

4 designates a cap or cover, having a flange 5 and lugs or projectionsto permit a firm gripping with the hand in operating it. The lower partof the flange is provided internally with an annular shoulder 7, andextending from this shoulder vertically is an annular surface 8,terminating in a second shoulder 9. From the shoulder 9 the inner sideof the flange is tapered inwardly in a slight degree to the top of thecap, forming an inclined annular surface 13.

The vertical surfaceS is provided with a series of vertically-arrangedelongated projections or lugs 10, preferably arranged in groups, andbetween the several .groups of projections 10 is a series ofhorizontally-arranged elongated ridges 11.

12 designates the lsealing-ringrlhis ring is preferably formed of amaterial ormaterials adapted to be softened when warmed by a littleartificial heat, as of a gas-flame. For example, a ring composed .ofasbestos fiber and paraflin or ofwax can be used; butI do not, ofcourse, confine myself tothe useof any particular materialorcompoundsolong as it is capable of cooperating in the invention asdesired. The ring can advantageously be formed of one or more layerscoiled one upon another, fas illustrated in Fig. 5.

ln practice the sealing-ring is Erst placed within the cover next theflange. The ring is Athen heated sufficiently to slightly soften it,when by turning thecap and ring down onto the threaded neck of the jalgas in turning a threaded `nut onto a bolt, the threads of the jarpenetrate the inner side of the sealing-ring and the sealing is'alsopressed under and around the projection 3a, while the ring at its outerside is pressed about the projections 10 and 11 in the cover. Inforcingthe cover downward the inclined surface 13 thereon cooperates with thetapered or inclined surface 14 and the shoulder 3 on the neck of thevessel to compressthe fibrous ring about the projections 10 and 11 andeffect a close tight joint between the vessel and cover.

As a result of the foregoing operations the ring becomes attached to thecover and the cover and ring together may be turned 0H the neck of thejar in a manner somewhat like that in which a threaded nut is turned offa bolt. It will be noted that the vertical projections 10 tend toprevent horizontal movement of the ring and cover with respect to eachother and that ythe horizontal projections 11 tend to prevent directvertical separation of the cover from the ring.

The form of sealing-ring shown in Fig. 5 is covered in application forPatent of the United States filed by me April 16, 1906, Serial No.311,904.

I/Vhat I claim, and desire to secure by Letters Patent, is-

1. Means for closing a vessel consisting of a cover provided with aiange having on its inner side projections lying at angles to eachother, and a sealing-ring to fit between said flange and the vessel.

IOO

2. Means for closing a vessel consisting of a cover provided with afiange having on its inner side a pluralityv of projections lying atangles to each other and alternating with each other around the flange,and a sealingring to fit between said flange and the vessel.

3. Means for closing a vessel consisting of a cover provided with afiange having on its inner side a plurality of projections arranged ingroups and at angles to each other and a sealing-ring to fit betweensaid flange and the vessel.

4. Means for closing a vessel having the periphery of its end providedwith projections, said closing means consisting of a cover provided witha flange having on its inner side projections lying at angles to eachother, and a sealing-ring to fit between said flange and the vessel andadapted to engage the projections of the vessel and cover.

5. Means for closing a vessel having the periphery of its end providedwith a thread, said closing means consisting of a cover pro vided .witha iiange having on its inner side projections lying at angles to eachother, and a sealing-ring adapted to engage the projections of the coverand the threads of the vessel.

6. Means for closing a vessel consisting of a cover provided with aflangeadapted to engage a sealing material, said flange also beingtapered inward at its upper end whereby it is adapted, when the cover isapplied to the vessel, to compress the sealing material between thevessel and flange and into engagement with the flange.

7. Means for closing a vessel having an annular shoulder below the upperend thereof, said means consisting of a sealing material, a flangedcover adapted to engage the sealing material, the iiange of said coveralso being tapered inward at its upper end whereby it is adapted tocoperate with the shoulder on the vessel to compress said sealingmaterial into engagement with said flange.

8. Means for closing a vessel having a thread on its end and a shoulderbelow said thread, said means consisting of a sealing material and aflanged cover adapted to be engaged by the sealing material, said flangebeing also tapered inward at its upper end to vcoperate with saidshoulder to compress the sealing material into engagement with saidflange.

- 9. Means for closing a vessel having a tapering end provided withmeans for engaging a sealing material and a shoulder below said engagingmeans, said closing means comprising a sealing material and a coverprovided with a flange having means thereon for engaging the sealingmaterial and an inwardly-tapering wall above said engaging means, saidtapering wall and said shoulder adapted to coperate to press the sealingmaterial into engagement with the flange of the cover.

lO. A vessel having a downwardly-facing shoulder around its neck andthreads below said shoulder, combined with a cover for said vessel and asealing-ring therein to coperate with said shoulder and threads. y

11. A vessel having a downwardly-facing shoulder around its neel-z, withan inwardlytapering face above said shoulder and threads on the neckbelow said shoulder, combined with a cover for said vessel and asealingring therein to coperate with said shoulder and threads.

In testimony whereof I aflix my signature in presence of two witnesses.
